This is why I don't participate in the newbie threads anymore. Last one I read was talking about his first fish he added to a newly cycled tank was a mandarin and how easy they are to keep. Tangs are fine in nanos and mandarins are effortless. If you don't believe that, you're just an old grouch. When i hear from uninformed but arrogant people like this, i regretfully think the whole hobby should be shut down. Many don't want advice, they just seek justification for something they already decided to do.
